It is very sturdy and not difficult to assemble, so I am puzzled as to why some say it is.  Some people commented on running the cords after installation and they were right.  Running the cords is difficult.  The hole for passing the wires through is on the bottom shelf which is very narrow and I couldn't put any equipment there if I wanted to.  I cut a circular hole behind the sliding door in the middle of the console on the back wall of the unit and placed a surge protector there.  I then ran the tv cord behind the unit and into the new hole.  I then I then ran all the equipment and wiring and had two people lift the unit off the bracket so I could pass the cables through the back of the unit to the ground.  You CANNOT pass cables from the top of the unit behind the console without removing the unit from the wall so plan for that as you are finalizing how you want the unit setup.
